Change to meta_or_ctrl for macos

[TokisanGames]

Description

On Macos ctrl+click is right-click and cannot be changed.

Instead change input detection to use Input.is_command_or_control_pressed(). Then the commands will be inverse: ctrl/cmd, alt mode: alt/option/keybind.

In the meantime, macos users can inverse by first clicking and holding, then pressing ctrl.

Hello, Yes for me it's totally impossible to remove region with ctrl + LMB (trackpad) MacOs

[TokisanGames]

Click+hold first, then press ctrl. Also sculpting and painting on a trackpad is extremely difficult anyway. I recommend getting an external mouse or tablet.

I have tried it with external mouse, it still doesn't work

[TokisanGames]

The recommendation for an external mouse is for general sculpting, independent of this issue. Ctrl+click won't work on any input device until we can replace the key in code. Click+hold first, then pressing ctrl is the only way to get removal to work on a mac at the moment.

Can one of you guys please edit editor.gd L272 and see if this works fine for you.

Change
modifier_ctrl = Input.is_key_pressed(KEY_CTRL)
to
modifier_ctrl = Input.is_key_pressed(KEY_CTRL) or Input.is_key_pressed(KEY_META)

It should change the cursor/toolbar when cmd is held, and perform the negative operation on cmd+click.

Fixed by #568. Would still like testers of the above comment and/or #568.

Hey! Thank you for looking into this! I tested this now on my MacBook Pro M2 15.1.1 on 0.9.3a and i found the above line at 276 instead.
If I move the mouse around the brush is white and when I left click the terrain is raised, as expected.
If I press and hold cmd and move the mouse around the brush is black instead and when I left click the terrain is lowered, so this seems to fix the issue!

Thanks for the report. The fix has been merged in to main which is usable in nightly builds, but you can continue using this manual fix in the current version.
